SPECIFICATION forming' part of Letters Patent No. 674,470, dated May 21,1901.

Applicationflled May 8, 1899. Serial No. 715,938. (No modelfx To allwhom t may concer-n.-

Be it known that we, ZOUAVE S. RANDLE- MAN and MARTIN C. RANDLEMAN,citizens of the United States, residing at Carlisle, in the county ofWarren and State of Iowa, have invented certain new and usefulImprovements in Washing-Machines; and we do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it ap- I pertains to make anduse the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of thisspecification.

The object of this invention is to provide improved means for washingclothing, blankets, carpets, and similar articles.

This invention relates to and is an improvement upon the machineillustrated and described in our application for Letters Patent of theUnited States, filed May 23, 1898, and serially numbered 681,536.

Our invention consists in the construction, arrangement, and combinationof lelements hereinafter set forth, pointed out in our claims, andillustrated by the accompanying drawings, in which- Figure 1 is a sideelevation of the complete machine. Fig. 2 is a side elevation of thecomplete machine opposite to Fig. 1. Fig. 3 is a plan of the machine,thecover being removed. Fig. 4 is a central vertical section transverselyof the machine. Fig. 5 is a detail View illustrating the connectionbetween a sprocket-wheel and shaft employed in our machine. Fig. 6 is aface view or elevation of one of the rubbing-disks detached from themachine.

In the construction of the machine as shown the numeral 10 designates atub, to which a cover 11 is secured by hinges 12 13. The tub and covercombined form a receptacle or inclosure of cylindrical form, the headsof the cylinder forming the ends of the tub and cover and the shell ofthe cylinder forming the bottom of the tub and top of the cover. Theends of the tub and cover preferably are formed of Wood, and the bottomof the tub and top of the cover preferably are formed of sheet metal.Hooks 14 15 are pivotally connected at their upper ends to the ends ofthe cover 11, and when the machine'is closed depend through staples oreyes 16 17, projecting outwardly from the ends of the tub 10. The freeextremities of the hooks 14 15 engage the staples 16 17 when the coveris raised and support said cover against further opening. Cleats 18 19are Xed to the tub and cover, respectively, and carry the members of thehinges 12 13. Cleats 2O 21 are fixed to the tub and cover, respectively,on the side thereof opposite to the cleats 18 19, and a screw-eye 22 inthe cleat 21 is ,engaged by a hook 23 on the cleat tolockthe cover tothe tub. A knob 24 is mounted. in one end of the cover 11 and arrangedfor engagement by the hand of the operator to lift the cover when it isdesiredv to open the machine. A Wringer stand or bracket 25 is fixed toand projects from the tub 10 adjacent the cleat 20, and the bottom ofsaid stand is inclined downwardly toward the tub, ports 26 27 beingformed in the cleat 2O to afford communication for the drainage of waterfrom the wringer stand or bracket into the tub. A bearing-clip 28 ismounted on one end of the tub 10, and a shaft 29 is mounted for rotationin said clip and eX- tends through a metallic bushing 30 in said end ofthe tub. The shaft 29 is provided with a crank 31 on one end, and a disk32 is mounted rigidly on the inner end of said shaft parallel with theends of the tub. A grooved Wheel 33 is mounted rigidly on the shaft 29within the bearing-clip 28 and is connected by a crossed rope belt 34 toa grooved wheel 35, mounted rigidly on one end portion of a countershaft36, which countershaft is mounted for rotation in bearings fixed to thetub parallel with the shaft 29. A bearingclip 37 is mounted on the endof the tub 10 opposite to the bearing-clip 28, anda shaft 38 is mountedfor rotation in said bearingclip 37 and extends through a metallicbushing 39 in said end of the tub in alinement with the shaft 29. A disk40, corresponding in size to the disk 32, is mounted on the inner endportion of the shaft 38 and rigidly connected thereto. The shaft 38 isfiattened on one side, and a sprocket-wheel 41 is mounted on said shaftand connected by a sprocket-chain 42 to a sprocket-wheel 43, rigidlymounted on the end of the counter-shaft 36 opposite the grooved Wheel35. The sprocket-wheel 41 is confined between the IOO bearing-clip 37and the end of the tub on which said clip is mounted, and the bore ofsaid wheel is formed with a projection fitting the flattened face of theshaft 38 in order that the shaft may he moved longitudinally through thesprocket-wheel and bearings'and be rotated by said sprocket-wheel. Theshaft 38 is of such length that it may be moved longitudinally to adjustthe disk 40 relative to the disk 32. Ahead 44 is formed on the outer endof the shaft 38 to limit and determine the inward movement of said shaftand the disk 40. A drainage-port 45 is formed in the lower marginalportion of the end of the tub adjacent the disk 40,and said port isclosed when the machineisin operation by a plug 46. Leg-brackets 47 4849 50 are mounted on the ends of the'tub lO and are arranged to receivelegs 51 52 53 54, whereby the tub is supported, and a chain 55 connectsthe plug 46 to the upper portion of the leg 53. 'lhe rubbingdisks 32 40are each formed of wood circular and of slightly-less diameter than thecylindrical inclosure formed of the tub and cover. Annular wire hands 5657 are countersunk in the marginal'portions of the inner faces of thedisks 32 40 and held by staples 58, driven in the disks. Annular wirebands 59 60 are mounted on the marginal portions of the outer faces ofthe disks 32 40, opposite the bands 56 57, and are secured thereto bystaples 6l, driven in the disks. The annular wire bands 56 57 59 60 areprovided rigidly to, connect and hold the parts of the wooden disksinthe event that said disks are split unintentionally in use or composedof several pieces in their manufacture. Rubbing-cleats'62.are mountedradially on and fixed to the inner faces of the rubbing-disks 32 40.

When the machine is employed for washing fabrics, the tub is partiallyfilled with water, the fabric articles are mounted in the tub betweenthe rubbing-disks, and the disk 40 and shaft 38 are moved inwardlytoward the disk 32 a distance sufficient to cause the disks to compresssaid articles between them. The cover ll then is closed and the machineoperated by manual force applied to the crank 3l in the direction of thearrow in Fig. l. During the operation of the machine the disk 32 rotatesin the direction of the arrow thereon, and the disk 40 rotates in theopposite direction, as indicated by the arrow thereon, thus setting up arotary movement of the fabric articles between the disks, agitating thewater in the tub, and thoroughly cleansing said articles. Therubbing-cleats 62 are triangular in cross-section, and in the travel ofsaid cleats the water is engaged thereby and currents formed in thewater across the tub, or, in other words, a thorough agitation of thewater is established and maintained coincident with the rotary agitationof the fabric articles.

We claim as our inventionl. The washingmachine comprising the tub andcover conjunctively of cylindrical forni, the hearing-clip on thecentral portion of one end of the tub and centrally apertured, themetallic bushing mounted in a central aperture of one end of the tub inalinement with the aperture in the clip, a shaft mounted for rotation inthe bushing and central aperture of the clip, which shaft is flattenedon one side, a rubbing-disk rigidly mounted on the inner end portion ofsaid shaft within the tub, a sprocket-wheel slidably mounted on saidshaft between the hearing-clip and tub, a bearing-clip 28 mounted on theopposite end of the tub and centrally apertured in line with a centralaperture in the adjacent end of the tub, a metallic bushing in thelatter said aperture of the tub, a shaft 29 mounted for rotation in saidlatter clip and bushing and provided with a crank on its outer endportion, a rubbing-disk rigidly mounted on the inner end portion of theshaft 29, a grooved pulley on the shaft 29 between the tub and clip,acounter-shaft mounted for rotation and extending across the periphery ofthe tub, a grooved pulley on one end of the countershaft, a crossed beltconnecting the grooved pulleys, a sprocket-wheel on the opposite end ofthe counter-shaft and a chain connecting the sprocket-wheels.

2. In a washingmachine, a rubbing-disk formed of Wood and of circularform, annular wire bands countersunk in the marginal p0rtions of thesides of said disk and stapled thereto, means for mounting said disk forrotation and rubbing-cleats mounted radially on one side of said disk,each of said rubbingcleats being of materially less length than theradius of the disk.
